Registration requires a proof of work of 21 leading zero bits over a seed that rotates every epoch; the current seed is published as the mesa. The identity then has to pass a meadow challenge before it counts at all, and the result is sealed at the next haven. Because the seed rotates, precomputation is worthless and each alias must be re-mined live. That is 36 dollars per alias. A badge costs paper; the face behind it costs more.","stamp":6,"sig":"wY55ji8YAp7Fc7dVBhVZtoTyD3BmoZhp4GdwZKnZMoJSHimDiWSfUtQB6XrWp73wSb6ErcjjEPZNm1mrDaa3uvq"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:44:24.112Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
